Yesterday, actress Rosario Dawson, who is a known supporter of Bernie Sanders and is very involved in politics, got into a little bit of a Twitter argument with actor John Leguizamo, who supports Hillary Clinton.

Sanders, for the record, has been under fire for weeks for his refusal to drop out of the campaign and allow left-leaning voters to coalesce behind Clinton ahead of the general election, which will see her fighting Donald Trump for the presidency.

With supporters as ardent as Dawson, it’s no surprise that Sanders plans to stay in and fight.
